In a rare and wide-ranging interview, the attorney general disclosed
chilling, new details about the evolving threat of homegrown terror, and
touched on topics ranging from Wikileaks to the prisoners at Guantanamo
Bay.

What was uppermost on his mind, however, is the alarming rise in the
number of Americans who are more than willing to attack and kill their
fellow citizens.

"It is one of the things that keeps me up at night," Holder said. "You
didn't worry about this even two years ago -- about individuals, about
Americans, to the extent that we now do. And -- that is of -- of great
concern."

"The threat has changed from simply worrying about foreigners coming
here, to worrying about people in the United States, American citizens
-- raised here, born here, and who for whatever reason, have decided
that they are going to become radicalized and take up arms against the
nation in which they were born," he said.
